Description

[0001] The invention relates to a sanitary fluid changeover device according to the preamble of claim 1 and to a sanitary shower equipped therewith according to the preamble of claim 7.

[0002] The sanitary fluid switching device accordingly comprises a base body with a fluid inlet, at least a first and a second fluid outlet, a first fluid path from the fluid inlet to the first fluid outlet and a second fluid path from the fluid inlet to the second fluid outlet as well as a switching element which is arranged in the base body so as to be movable between a first and a second setting position and for selectively blocking and opening the first and the second fluid path. In the first setting position, the switching element at least partially opens the first fluid path and at least partially blocks the second fluid path, while in the second setting position it at least partially closes the first fluid path and at least partially opens the second fluid path. In special embodiments, the switching element completely opens or closes the first fluid path in the first setting position.maximally free and / or completely blocks the second fluid path and / or completely blocks the first fluid path in the second setting position and / or completely or maximally frees the second fluid path. It is understood that, in addition to the two fluid outlets mentioned, the fluid switching device may have one or more additional fluid outlets, depending on the requirements and application, between which the user can switch using the switching element.

[0003] With this fluid diverter device, a fluid supplied via the fluid inlet, such as water, can be delivered optionally via the first fluid path at the first fluid outlet and / or via the second fluid path at the second fluid outlet. If the diverter element completely blocks one of the fluid paths in the respective setting position, the fluid is only delivered at the other outlet; with only partial blocking, the fluid can be divided between both outlets. Due to this functionality, such fluid diverter devices are used, for example, in the form of manually operated fluid diverter valves in bathtub fittings to deliver water optionally to a tub spout or a hand shower, as well as in overhead and hand showers that are designed to optionally deliver a shower jet in different jet types. Using the diverter valve, the user can set the desired shower jet type or switch between the different shower jet types.

[0004] For this purpose, the switching element conventionally forms a movable valve body that can be actuated by the user via an associated operating mechanism. The operating mechanism includes an operating element accessible to the user for actuation, which thus functions as the user interface of the operating mechanism, and a transmission mechanism that transmits the actuation of the operating element by the user to the switching element, which can be configured, for example, as a rotatable and / or axially movable valve disc body. Fluid switching devices of this type, in which a push button serves as the user interface and a disc-shaped, rotatable, and in some cases additionally axially movable valve body serves as the switching element, are disclosed in the patents DE 101 37 611 C1, US 6,622,945 B1, EP 2 213 918 B1, and DE 10 2016 213 489 B3.

[0005] The invention is based on the technical problem of providing a sanitary fluid switching device of the type mentioned at the outset, which offers novel, advantageous functionalities compared to the above-mentioned prior art, and a sanitary shower with such a fluid switching device.

[0006] The invention solves this problem by providing a sanitary fluid changeover device having the features of claim 1 and a sanitary shower head having the features of claim 7. Advantageous developments of the invention are specified in the subclaims, the wording of which is hereby incorporated by reference into the description. This includes, in particular, all embodiments of the invention resulting from the combinations of features defined by the references in the subclaims.

[0007] The sanitary fluid switching device according to the invention includes a user-accessible actuating member formed on the switching element for user-operated movement of the switching element between the first and the second switching position and a user-operated adjustable anti-twist device between a locking position and a release position, which in the locking position locks the switching element against user-operated movement between the first and the second setting position and in the release position releases the switching element for user-operated movement between the first and the second setting position.

[0008] Typically, the user-accessible actuating element, via which the user can move the switching element to effect the switching function, is formed on the switching element itself in this fluid switching device. A transmission mechanism between this user-accessible actuating element and the switching element that effects the desired fluid switching is therefore eliminated, which correspondingly keeps the complexity of the fluid switching device low.

[0009] Furthermore, this fluid changeover device typically features a user-operable anti-twist device, which allows the user to ensure that the changeover element remains in its current setting and cannot be adjusted. If the anti-twist device is in the corresponding locked position, the user cannot move the changeover element via the actuating element. Instead, the user must first move the anti-twist device to the release position, which then permits user-operated movement of the changeover element via the actuating element.

[0010] The fluid switching device according to the invention can be used very advantageously, for example, for sanitary shower heads whose design is fundamentally designed for selective delivery of the shower jet in various spray modes, but which are primarily intended to be operated in only one of these spray modes in the respective intended application. In this application, the user, in this case possibly also the manufacturer or installer, can permanently set the sanitary shower head to the desired spray mode by moving the switching element into the corresponding setting position via the actuating element accessible to them when the anti-twist device is in the release position, and then ensuring that the switching element maintains this setting position by moving the anti-twist device to the locked position.This use of the fluid switching device according to the invention is particularly useful when one and the same sanitary shower is never or only rarely to be switched between the shower jet types.

[0011] For example, an overhead shower model or hand shower model, the structure of which is optionally configured to deliver the shower jet in a first or a second shower jet type and is equipped with the fluid conversion device according to the invention, can be configured in a first application as an overhead / hand shower for delivering the first shower jet type and in a second application as a overhead / hand shower for delivering the second shower jet type. It remains possible for the user to convert the shower in question to the other shower jet type at a later time by converting the fluid conversion device accordingly, i.e. moving the anti-twist device from its locked position to its released position and adjusting the conversion element on the actuating member.

[0012] In a further development of the invention, the base body has a base contact surface with at least one first outlet opening leading to the first fluid outlet and at least one second outlet opening leading to the second fluid outlet, and the switching element includes a counter contact surface contacting the base contact surface with a passage opening contour that is in fluid communication with the fluid inlet and includes one or more passage openings in a manner known per se. This represents a structurally advantageous embodiment of the fluid switching device. Via the passage opening contour, the fluid can be guided from the fluid inlet to one and / or the other fluid outlet by appropriately adjusting the switching element. Alternatively, the switching element can be a valve body not provided with passage openings, which selectively blocks one or the other outlet opening.

[0013] In one embodiment of the invention, the switching element is a switching cup with a cup base that forms the counter-contact surface, wherein the actuating member protrudes radially outward from a circumferential surface of the switching cup, and the movement of the switching cup between the first and second setting positions is a rotational movement about a longitudinal axis of the switching cup. This represents a structurally and functionally advantageous implementation of the switching element. Alternatively, the switching element can be designed in a different way, e.g., as a rotatably movable disc body or as a translationally movable element.

[0014] In a further embodiment of the invention, the base body has a sleeve portion circumferentially surrounding the changeover cup, with a guide track extending in the circumferential direction of the sleeve. The actuating element is an actuating lug that engages the guide track. This represents a realization of the base body that is advantageously adapted to the configuration of the changeover cup. The base body simultaneously serves to guide the guide of the actuating element formed as an actuating lug. Alternatively, a different design can be selected for the base body, e.g., with a sleeve portion circumferentially surrounded by the changeover cup.

[0015] In a further embodiment of the invention, the slide track has a first axial recess into which the actuating lug engages when the changeover pot is in the first setting position and the anti-twist device is in the locking position and / or a second axial recess into which the actuating lug engages when the changeover pot is in the second setting position and the anti-twist device is in the locking position.

[0016] This design has the advantage that the changeover pot is secured against movement in the respective setting position by the engagement of the actuating lug in the corresponding axial guide track recess. The respective axial recess also facilitates precise reaching and remaining in the corresponding setting position. To adjust, the changeover pot must first be moved axially out of this recess with its actuating lug before it can then move with its actuating lug in the circumferential direction along the guide track toward the other setting position. Alternatively, the guide track can remain without such an axial recess if this is not beneficial for the respective application.

[0017] In yet another embodiment of the invention, the anti-twist device has a pressure element that can be attached to the base body so that it can be adjusted by the user between a locked position and a release position. In its locked position, this pressure element exerts an axial pressure force on the diverter pot, pressing it axially against the base contact surface with its pot base to prevent it from twisting and / or pressing its actuating lug into the first or second axial recess in the guide track. This represents an advantageous implementation of the anti-twist device. The user can use the pressure element to press the diverter pot with its pot base against the base contact surface of the base body and / or to press its actuating lug into the relevant axial recess in the guide track. In the former case, the locked position of the anti-twist device is achieved by the frictional engagement between the pot base and the base contact surface, in the latter case by the positive engagement between the actuating lug and the guide track recess.Alternatively, other known implementations for the anti-rotation device can be used, e.g. a locking pin that can be inserted into aligned openings on the diverter pot on the one hand and on the base body on the other.

[0018] The sanitary shower according to the invention includes a shower head which is configured to deliver fluid in one of several shower jet types and has a shower inlet and a first shower outlet for a first shower jet type and a second shower outlet for a second shower jet type, and the fluid switching device according to the invention which is configured to selectively bring the first or the second shower outlet into fluid connection with the shower inlet.

[0019] This sanitary showerhead therefore advantageously utilizes the fluid switching device according to the invention for the purpose of being able to switch the sanitary showerhead between different possible spray types. As explained above, this use of the fluid switching device according to the invention is particularly useful for showerheads where switching between spray types is never or only rarely required.

[0020] In a further development of the invention, the sanitary shower is an overhead shower, and the base body is formed by an inlet-side part of the shower head. This represents a structurally advantageous use of the fluid switching device according to the invention in an overhead shower. By integrating the base body into the inlet-side part of the shower head, the space required for the fluid switching device can be kept to a minimum. In particular, a corresponding overhead shower according to the invention can therefore have essentially the same external dimensions as a conventional overhead shower without the fluid switching device according to the invention but with an otherwise similar shower head structure.

[0021] In one embodiment of the invention, the sanitary shower includes a ball joint for pivoting the shower head around a connecting body, wherein the connecting body comprises a hollow joint ball, which is a component of the base body and in which the diverter cup is accommodated, and a pipe connection section. In this case, the sanitary shower also includes a pipe connection piece that can be inserted into the pipe connection section and acts as the pressure element of the anti-twist device. Thus, the ball joint used to pivot the shower head is advantageously used in addition to the integration of the fluid conversion device according to the invention. It should be noted at this point that the term "pipe" is used in a general sense and therefore includes in particular both rigid and flexible pipes and hoses or parts thereof.

[0022] Advantageous embodiments of the invention are illustrated in the drawings. These and other embodiments of the invention are explained in more detail below. In the drawings: Fig. 1 is an exploded perspective view of a fluid switching device suitable for use in a shower, Fig. 2 is a perspective view of a switching element of the fluid switching device configured as a switching pot, Fig. 3 is a perspective view of a base body of the fluid switching device with an integrated shower joint ball, Fig. 4 is a plan view of the fluid switching device with the switching element in a first setting position, Fig. 5 is a view of Fig. 4 with the diverter element in a second setting position, Fig. 6 a partial longitudinal sectional view of a sanitary shower configured as a head shower with the fluid diverter device of the Fig. 1 to 5and the switching element in the second setting position, Fig. 7 a longitudinal sectional view of a part of Fig. 6 in one to Fig. 6 vertical section plane, Fig. 8 a longitudinal section view similar Fig. 7 with the switching element in the first setting position and Fig. 9 a longitudinal sectional view of the fluid switching device in a position similar to that of Figs. 6 and 7 rotated cutting plane.

[0023] As illustrated in the figures based on the embodiment shown there, the sanitary fluid switching device according to the invention comprises a base body 1, a switching element 7 in the base body 1 and an anti-twist device 9. The base body 1 has a fluid inlet 2 as well as a first fluid outlet 3 and a second fluid outlet 4. A first fluid path 5 leads from the fluid inlet 2 to the first fluid outlet 3, a second fluid path 6 leads from the fluid inlet 2 to the second fluid outlet 4. Depending on requirements and application, one or more additional fluid outlets with associated fluid paths can be provided.

[0024] The switching element 7 is in the base body 1 between a first setting position E1, see for example the Figures 4 and 8 , and a second setting position E2, see for example the Figures 5 , 6 and 7, movably arranged in order to be able to selectively block off or open the first fluid path 5 and the second fluid path 6. For this purpose, the switching element 7 in the first setting position E1 at least partially opens the first fluid path 5, completely in the example shown, and at least partially blocks the second fluid path 6, completely in the example shown. Analogously, the switching element 7 in the second setting position E2 at least partially blocks the first fluid path 5, completely in the example shown, and at least partially opens the second fluid path 6, completely in the example shown. Furthermore, the fluid switching device includes a user-accessible actuating member 8 formed on the switching element 7 for user-operated movement of the switching element 7 between the first switching position E1 and the second switching position E2.

[0025] The fluid switching device also has an anti-rotation device 9, which can be adjusted by the user between a locked position and a released position. In the locked position, the anti-rotation device 9 blocks the switching element 7 from being moved by the user between the first setting position E1 and the second setting position E2. In the released position, the anti-rotation device 9 releases the switching element 7 for user-operated movement between the first setting position E1 and the second setting position E2.

[0026] In advantageous embodiments, the base body 1 includes a base contact surface 10 with at least one first outlet opening 11 leading to the first fluid outlet 3 and at least one second outlet opening 12 leading to the second fluid outlet 4. The switching element 7 includes a counter-contact surface 13 contacting the base contact surface 10 with a passage opening contour 14 that is in fluid communication with the fluid inlet 2 and includes at least one passage opening. In the example shown, the fluid switching device is configured in this way, with the passage opening contour 14 including two passage openings 14 1 , 14 2 .

[0027] In advantageous embodiments, the switching element 7, as in the example shown, is configured as a switching pot 15 with a pot bottom 15a, which forms the counter contact surface 13. The actuating member 8 protrudes radially outward from a lateral surface 15b of the switching pot 15, as can be seen, for example, from the Figures 1, 2 , 7 and 8 The movement of the changeover pot 15 between the first setting position E1 and the second setting position E2 is realized in this case as a rotational movement about a longitudinal axis TL of the changeover pot 15.

[0028] In corresponding embodiments, the base body 1, as in the example shown, has a sleeve part 1a surrounding the changeover pot 15 on the circumference with a guide track 16 running in the sleeve circumferential direction, as for example from Fig. 1Specifically, in the example shown, the slide track 16 extends between the two setting positions E1, E2 over a cup circumference angle of approximately 90°. In this case, the actuating element 8 is configured as an actuating lug 17 that engages the slide track 16.

[0029] In advantageous implementations, the slide track 16 includes a first axial recess 18, into which the actuating lug 17 engages when the changeover pot 15 is in the first setting position E1 and the anti-rotation device 9 assumes its locking position, and / or a second axial recess 19, into which the actuating lug 17 engages when the changeover pot 15 is in the second setting position E2 and the anti-rotation device 9 assumes its locking position. In the example shown, both the first axial recess 18 and the second axial recess 19 are present; in alternative embodiments, only one of the two recesses 18, 19 or neither of them is present.

[0030] In advantageous embodiments, the anti-rotation device 9 has a pressure element 20 that can be attached to the base body 1 and can be adjusted by the user between a locked position and a release position in order to provide the respective locked position or release position of the anti-rotation device 9. In the locked position, the pressure element 20 exerts an axial pressure force on the changeover pot 15, which presses the changeover pot 15 with its pot bottom 15a axially against the base contact surface 10, securing it against rotation, and / or presses its actuating nose 17 into the first axial recess 18 or the second axial recess of the guide track 16.The example shown has the anti-twist device 9 in this configuration, wherein the changeover pot 15 is secured against twisting both by frictional engagement of the pot bottom 15a pressed against the base contact surface 10 and by positive engagement of its actuating lug 17 pressed into the relevant axial recess 18, 19.

[0031] As also illustrated in the figures using an exemplary embodiment, the sanitary shower according to the invention comprises a shower head 21 which is designed to deliver fluid in one of several shower jet types and for this purpose has, in a manner known per se, a shower inlet 22 and a first shower outlet 23 for a first shower jet type and a second shower outlet 24 for a second shower jet type. Fig. 6shows the exemplary design of the sanitary shower in a partial longitudinal sectional view of the part of interest here, which can in particular be an overhead shower. The two different shower jet types can be, for example, a gentle jet and a massage jet, or a fine, misty shower jet and a rain-like shower jet. The two shower outlets 23, 24 are represented by corresponding jet outlet openings of the shower head 21. Depending on the system design, the different jet types can each be assigned their own jet outlet openings, or the respective jet outlet opening can emit both jet types through a different fluid supply and suitable design.

[0032] The sanitary shower according to the invention is equipped with a sanitary fluid changeover device 25, which is a sanitary fluid changeover device according to the invention, in the example shown in particular a fluid changeover device of the type described in the Figures 1 to 5 and 9 The fluid switching device 5 is configured to selectively fluidically connect the first or second shower outlet 23, 24 to the shower inlet 22. For this purpose, the first shower outlet 23 is fluidly connected to the first fluid outlet 3 of the fluid switching device 25, and the second shower outlet 24 is fluidly connected to the second fluid outlet 4 of the fluid switching device 25.

[0033] Specifically, the sanitary shower can be a head shower in which the base body 1 of the fluid switching device 25 is formed by an inlet-side part 21 a of the shower head 21, as realized in the example shown.

[0034] In advantageous embodiments, the sanitary shower comprises, as in the example shown, a ball joint 26 for pivoting the shower head 21 around a connecting body 27, which has a hollow joint ball 28 and a pipe or hose connection section 29. The hollow joint ball 28 is a component of the base body 1 and accommodates the diverter pot 15, i.e., the fluid diverter device 25 is, in this case, integrated into the ball joint area of the sanitary shower.

[0035] The sanitary shower head also includes a pipe or hose connection piece 30 that can be inserted into the pipe connection section 29 in a manner known per se. For example, the pipe connection piece 30 can be screwed or plugged into the pipe / hose connection section 29 and secured against axial movement by means of a locking screw or clamping screw 31. In the example shown, the pipe connection piece 13 functions as the pressure element 20 of the anti-twist device 9. For this purpose, when inserted into the pipe connection section 29, it presses axially against the facing end face of the diverter cup 15, whereby the diverter cup 15 is pressed with its cup bottom 15a against the base contact surface 10 of the base body 1 and is pressed with its actuating lug 17 into one of the two axial recesses 19 of the guide track 16, whereby the anti-twist device 9 is in its locked position.

[0036] To release this anti-twist device 9, the user moves the pipe connection piece 30 at least a short distance axially out of the pipe connection section 29, e.g. by screwing on the associated thread or after loosening the locking screw 31, so that the frictional connection between the pot base 15a and the base contact surface 10 is released and the user can move the changeover pot 18 axially back by actuating the actuating lug 17 until the actuating lug 17 comes out of the relevant axial recess 18, 19 and the changeover pot 15 can then be rotated from one setting position E1, E2 to the other about its longitudinal axis TL, for which purpose the user moves the actuating lug 17 accordingly along the guide track 16. To facilitate actuation, the actuating lug 17 can be provided with a tool interface 32, for example for attaching an actuating pin or a screwdriver.

[0037] In the embodiment shown, the base body 1 is essentially cylindrical and comprises, as already mentioned, the sleeve part 1a, which surrounds the diverter pot 15 on the circumference, and the joint ball 28 for the ball joint 26 of the shower as well as the pipe connection section 29 for inserting the pipe connection piece 30. The first fluid outlet 3 opens axially from this cylindrical base body 1, the second fluid outlet 4 opens radially outwards from the cylindrical base body 1.

[0038] The base contact surface 10 is provided in this example with two first outlet openings 11 and two second outlet openings 12, which are each diametrically opposite one another and each extend over a circumferential angle of slightly less than 90° in a triangular shape from a radial outer edge of the exemplary circular base contact surface 10 radially inward at a distance from the center of the base contact surface 10. Correspondingly, the passage opening contour 14 of the switching element 7 in the embodiment shown comprises the two passage openings 14 1 , 14 2 in diametrically opposite triangular shape, as can be seen, for example, from the Figures 1 , 4 and 5 visible.

[0039] In the illustrated embodiment, the pot base 15a of the changeover pot 15 is provided with a sealing body 33, which can be clipped axially from the outside onto the pot base surface and ensures the required fluid tightness as well as the anti-rotation frictional engagement with the base contact surface 10 of the base body 1. In Fig. 9 the frictional and sealing contact of the disc-shaped sealing body 33 against the base contact surface 10 of the base body 1 can be clearly seen.

[0040] In corresponding designs, the diverter pot 15 has a receiving space for accommodating one or more additional functional elements. In the example shown, a particle sieve 34 and a flow restrictor 35 are accommodated in the diverter pot 15, see, for example, Fig. 9 . Additionally or alternatively, a backflow preventer or a check valve can also be accommodated in the diverter pot 15.

[0041] Fig. 4shows a plan view of the fluid switching device in the first setting position E1 of the switching element 7, in which the latter releases the fluid connection from the upstream fluid inlet 2 to the first outlet openings 11 and thus to the first fluid path 5, which leads to the first fluid outlet 3, via its through-openings 14 1 , 14 2 .

[0042] Fig. 5 shows the fluid switching device with the switching element 7 in the second setting position E2, rotated by 90°, in which the fluid connection from the fluid inlet 2 via the passage openings 14 1 , 14 2 to the second outlet openings 12 of the base body 1 and thus to the second fluid path 6 is released, which leads to the second fluid outlet 4. In the example shown, the other fluid path 6 or 5 is completely blocked by the switching element 7 when it is in the first or second switching position E1, E2.

[0043] As the illustrated and further explained embodiments make clear, the invention advantageously provides a sanitary fluid changeover device and a sanitary shower that can be equipped with it. When used in the sanitary shower, the fluid changeover device offers, in particular, the possibility of configuring the sanitary shower in its design to accommodate several different shower jet types. The fluid changeover device can then be used to permanently adjust or set the actual shower jet type provided by the shower in a selectable and, if necessary, variable manner. This can be easily integrated into the design of the sanitary shower without requiring significant additional space.

[0044] As explained, the sanitary fluid changeover device can be used in particular in shower heads and especially in overhead showers. However, it is understood that the fluid changeover device can also be used for hand showers and bathtub fittings, as well as other applications, e.g., in garden irrigation technology, provided that there is a need to set a fitting designed for multiple operating modes, e.g., shower jet types, to a specific operating mode, while also being able to change this setting if necessary.
